Description
Technical field
The invention belongs to bus communication technology field, and in particular to a kind of bus network communication system and its method.
Background technology
The most frequently used communication mode is RS-485 communication modes in current bus warning system, using two-wire system wiring side
Formula, RS-485 maximum communication distances are 1200 meters.Using the system architecture of RS-485 bus communication modes, alarm host machine can access
A plurality of 485 bus line, in 1200 meters that every bus is extended, bus communication module, bus can be accessed in an arbitrary point
Communication module by front-end detector signal by 485 bus transfers to alarm host machine, realize long-distance alarm, this warning system
Structure is widely used among the environment such as school, museum, building, industrial enterprise.Its existing advantage of bus system, but in reality
There is also following defect in：
1) it is higher to bus line structural requirement, optimal wire laying mode be in bus between all modules using " pulling
The mode of hand " enters row bus connection, i.e., using the bus topology structure of daisy chain.Generally, 485 buses are not used as far as possible
Planet-shaped connecting wiring enters in a plurality of branch, may so cause communication unstable, because hub-and-spoke configuration can produce reflected signal, from
And have influence on 485 communications.Bus should be as far as possible short to branch's line length of each terminal device, and 5 meters are not got higher than typically.Branch line
If not connecing terminal, reflected signal is had, stronger interference is produced to communication.
2) higher is required to bus line wiring environment, all 485 bus communication signal wires should try one's best away from interference source, letter
Number line should walk light current well, forbid and forceful electric power (such as 220V residential powers) or radiofrequency signal circuit (such as CATV, big signal tone frequency channel wire)
And walking line, if simultaneously walking line, distance should be greater than 2 meters, it can not band together.The place of highfield is also contemplated that using plating
Zinc pipe is shielded.
3) later maintenance cost is higher, because all bus apparatus share the bus of same 485, if a certain in bus
Module breaks down, and such as bus short circuit certainly will so cause the failure of whole piece bus line, cause the module of other in bus also without
Method is recognized by the system, and causes whole system to be paralysed, and later period maintenance needs to spend the module check one by one of a large amount of manpowers, time, until
Find malfunctioning module and solve problem.
